GTX 770 vs R9 280 X?

which one is better for gaming ? 

and will it benefit my build ?

and also do i have to overclock my CPU to get a real performance gain ?


this is my build


the games i most of the time play are rome 2 total war , battelfield 4 and civilization 5 




You consider an upgrade to these cards from a I sad in the other topic, it's not worth it.

i would personaly go with FX8350 or FX8320 Asus M5A99FX pro R2.0 motherboard. and a R9-280X. because BF at mantle can utilize  more cores.

i dont see where hes got a 7950, if he allready has a 7950 with an overclock it can come close a a 7970 and even beats a GTX770 in some games, so in therms of that its not worth it then. ☺then its better to stay with the 7950 safe you some money and trow a GTX780 or amd R9-290 (X) in it later on.
